Chapter 4
BIOS
4-1 Introduction
This chapter describes the AMI BIOS Setup Utility for the X8DAH+/X8DAH+-F/ X8DAH+(-F)-LR. The AMI ROM BIOS is stored in a Flash EEPROM and can be easily updated. This chapter describes the basic navigation of the AMI BIOS Setup Utility setup screens.
Warning: For your system memory to work properly, be sure to use the correct BIOS ROM for your system.
For the X8DAH+, use the X8DAH+ BIOS. For the X8DAH+-LR, use the X8DAH+-LR BIOS. For the X8DAH+-F, use the X8DAH+-F BIOS. For the X8DAH+-F-LR, use the X8DAH+-F-LR BIOS.
Starting BIOS Setup Utility
To enter the AMI BIOS Setup Utility screens, press the <Delete> key while the system is booting up.
Note: In most cases, the <Delete> key is used to invoke the AMI BIOS setup screen. There are a few cases when other keys are used, such as <F1>, <F2>, etc.
Each main BIOS menu option is described in this manual. The Main BIOS setup menu screen has two main frames. The left frame displays all the options that can be configured. Grayed-out options cannot be configured. Options in blue can be configured by the user. The right frame displays the key legend. Above the key legend is an area reserved for a text message. When an option is selected in the left frame, it is highlighted in white. Often a text message will accompany it. (Note: the AMI BIOS has default text messages built in. Supermicro retains the option to include, omit, or change any of these text messages.)
The AMI BIOS Setup Utility uses a key-based navigation system called "hot keys". Most of the AMI BIOS setup utility "hot keys" can be used at any time during the setup navigation process. These keys include <F1>, <F10>, <Enter>, <ESC>, ar- row keys, etc.
Note 1: Options printed in Bold are default settings.
Note 2: For AMI BIOS Recovery, refer to the AMI BIOS Recovery Instruc- tions posted at http://www.supermicro.com/support/manuals/.
